The chapters on diamond have been revised in order to bring the discussion more in line with modern knowledge. In the cases of emerald and ruby and sapphire new sources of supply have necessitated additional text to the chapters on these gemstones. Minor adjustments have been made to other parts of the text and some new and unused gem materials have been mentioned where it is known that cut stones are in the hands of collectors.

The alteration of place names, particularly those of the new republics of Africa and Asia, has caused problems. Where possible these new names are put in the section headings, but they may not be continued throughout the text, for the older names are still in current circulation and are much better known. New designs of testing instruments are described and something is told of the more unusual instruments and techniques used by highly equipped laboratories coupled to universities, museums and large industrial concerns which have these types of apparatus for research and control.

These are often made available when normal gem-testing methods fail to provide an answer. Robert Webster xx Preface to the Second Edition Experience with the two volumes of the first edition has shown that a single volume would be more convenient to the user.

New tables on plastics and their identification, drawn up by Mr H Lee, will provide more help in dealing with the identification of these difficult materials, and separate tables on refractive indices and specific gravities have been included to supplement the comprehensive main table of constants.

The new blue zoisite gemstone, Tanzanite, has called for an alteration in the text.

Handbook of Gems

My thanks go to the many friends all over the world who have sent me items of information, or pointed out errors of omissions in the first edition.

Dr Kurt Nassau has been most helpful in advising on the newer synthetic stones and Mr Craig C Smith gave valuable information on the new chrome chalcedony found in Rhodesia. The staff of both western and eastern headquarters of the Gemological Institute of America gave helpful advice, and I must give my thanks to Mr B W Anderson for his ever-ready assistance, advice and criticism.

New coloured plates, with a somewhat different outlook, replace those of Hallwag used in the first edition, as these earlier plates are no longer available. During this period, new materials have been found and testing methods greatly improved, so that the simple expositions given in Practical Gemmology do not now cover the subject adequately and a new book has become a necessity. The majority of books written on the subject of gems start with a detailed account of the physical and optical properties of gem materials.

They then go on to the theory and use of instruments used in gem-testing before describing the gems themselves. In this work, the usual scheme is reversed and a more practical approach is made.

A short introduction to the formation of such minerals in the earth leads to descriptions of the various gem materials. Following this, there are chapters on synthetic stones, composite and imitation stones, and how gemstones are fashioned for the market. The first volume concludes with descriptions of pearl, coral, jet and amber, and other materials used in ornamentation which owe their genesis to organic processes.

The second volume deals with the technical aspects of gem materials and is followed by descriptions of the various methods used in gem identification. The book is completed by a section containing tables and useful data. The arrangement of describing the gemstones themselves before their technical aspects may be considered open to objection as some technical data must be included in the description of the stones. This is a minor point against the value of an arrangement which introduces the subject in the logical sequence of the finding in the rough state of the natural gems, the production of synthetic and imitation stones, and the fashioning of xxiii Preface to the First Edition these various natural and man-made materials into a finished gemstone.

Where possible, some simple explanation of the meaning of the technical references is brought out as the gem story unfolds. One problem which besets any writer on gemstones is to select the order in which the gem materials are discussed. Whatever method is used, some criticism is inevitable.

In this work the better-known jewellery stones are placed first, and are followed by the lesser-known stones in alphabetical order, unless, for some reason, the stones are better placed in a group forming a small subchapter.

In this section, too, are details of the use and working of a number of special instruments not usually included in such books.

Throughout the compilation of this work considerable assistance has been received from many members of the Gemmological Association and of the jewellery trade. I owe much to my colleagues Mr B W Anderson and Mr C J Payne for their encouragement and for unstintingly supplying me with much of their data accumulated in the archives of the Laboratory of the London Chamber of Commerce.

Further, Mr Anderson freely handed over to me much of his unpublished work on the causes of colour, the hardness and the methods of determining the density of gemstones. These notes have been duly incorporated in the text. If you are interested in sponsoring a class in your area, please contact us.
